To explore the advantages of traditional Chinese medicine （TCM） and integrative TCM-Western medicine approaches in the treatment of diabetic microvascular complications （DMC）， refine key pathophysiological insights and treatment principles， and promote academic innovation and strategic research planning in the prevention and treatment of DMC. The 38th session of the Expert Salon on Diseases Responding Specifically to Traditional Chinese Medicine， hosted by the China Association of Chinese Medicine， was held in Beijing， 2024. Experts in TCM， Western medicine， and interdisciplinary fields convened to conduct a systematic discussion on the pathogenesis， diagnostic and treatment challenges， and mechanism research related to DMC， ultimately forming a consensus on key directions. Four major research recommendations were proposed. The first is addressing clinical bottlenecks in the prevention and control of DMC by optimizing TCM-based evidence evaluation systems. The second is refining TCM core pathogenesis across DMC stages and establishing corresponding "disease-pattern-time" framework. The third is innovating mechanism research strategies to facilitate a shift from holistic regulation to targeted intervention in TCM. The fourth is advancing interdisciplinary collaboration to enhance the role of TCM in new drug development， research prioritization， and guideline formulation. TCM and integrative approaches offer distinct advantages in managing DMC. With a focus on the diseases responding specifically to TCM， strengthening evidence-based support and mechanism interpretation and promoting the integration of clinical care and research innovation will provide strong momentum for the modernization of TCM and the advancement of national health strategies.

Objective To evaluate the safety and efficacy of a self-developed micro-normothermic machine perfusion (NMP) system (micro-perfusion device) for preserving isolated porcine limbs. Methods Five healthy Landrace pigs were selected, and their left and right forelimbs were randomly divided into the NMP group and static cold storage (SCS) group. The NMP group was perfused with the self-developed micro-perfusion device and polymerized hemoglobin perfusate for 32 hours at normothermia, while the SCS group was preserved at 4 ℃. Hemodynamic parameters such as perfusion pressure and flow were monitored. The pH value, partial pressure of oxygen (PO₂), lactic acid (Lac), creatine kinase (CK) and lactate dehydrogenase (LDH) in the perfusate were measured. Hematoxylin-eosin staining was used to assess the muscle tissue structure, terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling was employed to evaluate muscle cell apoptosis, and immunohistochemistry staining was applied to detect the expressions of tumor necrosis factor (TNF)-α and interleukin (IL)-6. A mixed-effects model was used to analyze the effects of time and treatment methods on tissue structure, cell apoptosis and inflammatory factors. Results The device could stably maintain a perfusion pressure of (69±15) mmHg and a flow rate of (117±42) mL/min. The pH value and electrolytes of the perfusate were generally stable, with PO₂ maintained at a high level. Lac was maintained at 5.38(3.81, 6.45) mmol/L, while CK and LDH increased over time. After 32 hours of perfusion in the NMP group, both the myocyte spacing and apoptosis rate were better than those in the SCS group. Mixed-effects model analysis showed that there were statistically significant differences in the effects of NMP treatment and SCS treatment on myocyte spacing and apoptosis rate per unit time (both P < 0.05). There were no statistically significant differences in TNF-α and IL-6 between the two groups, and mixed-effects model analysis showed no statistically significant differences in the effects of NMP treatment and SCS treatment on TNF-α and IL-6 per unit time (both P > 0.05). Conclusions The micro-perfusion device used in this study may achieve 32-hour normothermic preservation in a porcine limb amputation model, maintain basic metabolism and ionic homeostasis, reduce muscle structural damage and cell apoptosis without inducing additional inflammatory responses. This technology is expected to significantly extend the time window for replantation of amputated limbs in disaster rescue and long-distance transportation, providing an important technical basis for clinical translation and subsequent replantation research.

ObjectiveMicrotube associated protein-2 （MAP-2）， alpha-tubulin （α-tubulin）， and synaptophysin （SYP） are important proteins in neuronal signal communication. This paper observed the effects of modified Zhigancao Tang on the expression of serum α-Synuclein （α-Syn） and its oligomers， MAP-2， α-tubulin， and SYP of patients with liver and kidney deficiency of Parkinson's disease （PD）， analyzed their correlation， and evaluated the therapeutic effect of modified Zhigancao Tang in patients with liver and kidney deficiency of PD based on α-Syn transmission pathway mediated by neuronal communication in vivo. MethodsA total of 60 patients with PD who met the inclusion criteria were randomly divided into a treatment group （30 cases） and a control group （30 cases）. Both groups were treated on the basis of PD medicine， and the treatment group was treated with modified Zhigancao Tang. Both groups were treated for 12 weeks. The changes in UPDRS score， TCM syndrome score， and expression of serum α-Syn and its oligomers， MAP-2， α-tubulin， and SYP were observed before and after 12 weeks of treatment in each group. The correlation between the above-mentioned serum biological indexes and the levels of serum α-Syn and its oligomers was analyzed. ResultsAfter treatment， the TCM syndrome score， UPDRS score， UPDRS-Ⅱ score， and UPDRS-Ⅲ score of the treatment group were significantly decreased （P<0.05， P<0.01）. The UPDRS score， UPDRS-Ⅱ score， and UPDRS-Ⅲ scores in the treatment group were significantly decreased compared with those in the control group after treatment （P<0.05）. After treatment， the total effective rate of the control group was 63.3% （19/30）， and that of the treatment group was 86.7% （26/30）. The clinical effect of the observation group was better than the control group （Z=-2.03， P<0.05）. The total effective rate of the observation group was better than that of the control group， and the difference was statistically significant （χ²=5.136， P<0.05）. After treatment， the oligomer level of serum α-Syn and MAP-2 level in the treatment group were significantly decreased （P<0.05， P<0.01）. The levels of serum α-Syn and its oligomers， as well as α-tubulin in the treatment group， were significantly decreased compared with those in the control group after treatment （P<0.05， P<0.01）. Serum α-Syn was correlated with serum MAP-2 and α-Syn oligomer in patients with PD （P<0.05， P<0.01） but not correlated with serum SYP . Serum α-Syn oligomers of patients with PD were correlated with serum MAP-2 and α-tubulin （P<0.05， P<0.01） but not correlated with serum SYP level. Serum SYP of patients with PD was correlated with serum MAP-2 （P<0.05）. ConclusionModified Zhigancao Tang has a therapeutic effect on patients with liver and kidney deficiency of PD by inhibiting the production of α-Syn oligomers and intervening α-Syn microtubule transport pathway in vivo.

In recent years,the global consumption of ultra-processed foods(UPFs)has increased.UPFs are classified as the fourth group of food in the NOVA classification system:industrially formulated foods made entirely or mostly from substances extracted from foods(oils,fats,sugar,starch,proteins,etc),derivatives of food constituents(hydrogenated fats,modified starches,etc),or multiple food additives.Common manufacturing techniques include extrusion,moulding,and pre-frying.As high-energy-density foods,UPFs are typically characterized by high levels of sugar,fat,and salt,and low levels of dietary fiber,protein,vitamins,and minerals,resulting in low nutrient density.Studies have shown that a high intake of UPFs increases the risk of various chronic diseases.Nutrition during pregnancy is a crucial factor influencing pregnancy outcomes,and balanced and adequate nutrient intake is essential for the health of both the mother and child.Given that UPFs have limited nutritional density,high intake during pregnancy may be detrimental to maternal and infant health.However,the impact of consuming UPFs during pregnancy on maternal and infant health is not extensively studied.This article reviews the literature on the effects of UPFs on pregnancy outcomes,aiming to provide a foundation for further research and personalized dietary guidance.

OBJECTIVE To explore the possible molecular mechanism through which amygdala cell adhesion molecule-1(CADM1)is involved in acute sleep deprivation-induced anxiety.METHODS Sixteen 8-week-old C57BL/6J mice were randomly divided into the control group and para-chlorophe-nylalanine(PCPA)-induced acute sleep deprivation experimental group.The PCPA mice were intraperi-toneally injected with PCPA suspension(at a dose of 300 mg?kg-1)between 8∶00 and 9∶00 am for 2 consecutive days while the control mice were injected with the same dose of normal saline.The sleep latency and sleep duration of mice were detected via the righting reflex test.Anxiety-like behaviors were detected by the open field test and elevated plus maze test.The expression level of CADM1 in the mouse amygdala was detected by Western Blot and Immunofluorescence staining.The GeneNet-work database was used to analyze the association between Cadm1 genes and other genes in the mouse amygdala.The key candidate regulatory genes were screened,and the Cadm1-anxiety behavior phenotype network was constructed.The mRNA expression levels of the key candidate regulatory genes were analyzed via qPCR analysis.RESULTS Compared with the control mice,the sleep latency of PCPA mice was significantly prolonged(P<0.01)while the sleep duration was significantly shortened(P<0.01).The activity time and distance of PCPA mice in the open field center were significantly shorter than those of the control group(P<0.05).The elevated plus maze experiment showed that the percentage of the number of times PCPA mice entered the open arm and the percentage of residence time in the open arm were significantly lower than those of the control group(P<0.05).Western Blot and immuno-fluorescence staining showed that the expression of CADM1 protein in the amygdala from PCPA mice was down-regulated compared with the control mice(P<0.05).Based on gene-behavioral association network analysis,Cadm1 was significantly associated with 25 anxiety-like behavior-related genes.The enrichment analysis of Cadm1 co-expression genes showed that Cadm1 was associated with γ-amino-butyric acid GABAergic synaptic pathway(P=4.31e-09),and that the key genes were huntingtin associ-ated protein 1(Hap1)(r=0.705,P=1.09e-08)、inositol 1,4,5-triphosphate receptor type 1(Itpr1)(r=-0.751,P=3.34e-10)、gamma-aminobutyric acid type A receptor subunit delta(Gabrd)(r=-0.836,P=3.93e-14)、γ-aminobutyric acid A receptor β1 subunit gene(Gabrb1)(r=0.732,P=1.50e-09)and adrenoceptor alpha 2A(Adra2a)(r=0.759,P=1.73e-10).The results of qPCR analysis showed that the mRNA levels of Hap1(P<0.05)、Gabrb1 and Adra2a were significantly up-regulated(P<0.01)while those of Itpr1 and Gabrd were significantly down-regulated(P<0.01).CONCLUSION Acute sleep deprivation leads to down-regulation of Cadm1 expression in the amygdala,and induces anxiety-like behaviors by affecting the expression of GABAergic synaptic signaling pathways Hap1,Gabrb1,Adra2a,Itpr1 and Gabrd.

Objective:To investigate the clinical and genetic characteristics of patients with amyotrophic lateral sclerosis (ALS) caused by FUS gene mutations. Methods:A retrospective analysis was conducted on 7 families diagnosed with FUS gene related ALS in the Department of Neurology of Henan Provincial People′s Hospital from January 2018 to June 2024. Clinical data and neuroelectrophysiological results of the probands and family members were collected. Next generation sequencing or whole exome sequencing was conducted on the probands. The detected variants of the FUS gene were confirmed by Sanger sequencing. Results:Among the 7 probands, 4 were with familial ALS and 3 with sporadic ALS, including 6 males and 1 female. The average age of onset was 24.6 years (ranging from 21 to 30 years). The onset site included bulbar muscles in 1 case, proximal upper limbs in 3 cases, proximal lower limbs in 2 cases, and both upper and lower limbs in 1 case. Four patients presented both upper and lower motor neurons involvement on examination, and 3 had only lower motor neuron syndrome. Muscle atrophy and fasciculation were observed in 6 patients respectively, and dyspnea in 3 patients. Bilateral muscle strength was asymmetric in 5 patients. Proximal muscle weakness was predominant in 6 of the 7 patients with upper limb weakness, and 3 of the 5 patients with lower limb weakness. Electromyography showed neurogenic damage in all 7 cases. Five heterozygous variants of the FUS gene were detected in 7 patients, including 2 patients with c.1574C>T(p.P525L), 2 with c.1552A>G(p.R518G), 1 with c.1561C>T(p.R521C), 1 with c.1441delC(p.R481Efs *48), and 1 with both c.1574C>T(p.P525L) and c.430_447del(p.G144_Y149del) variants. The variant c.1441delC(p.R481Efs *48) had not been previously reported. During follow-up, 6 patients died of respiratory failure 6-18 months after onset, with an average of 11.8 months. Conclusions:Patients with FUS gene related ALS have an early age of onset, rapid progression, short survival period, asymmetric limb weakness, and more severe involvement of proximal limbs. The c.1574C>T(p.P525L) is a hotspot mutation, and the novel variant c.1441delC(p.R481Efs *48) enriches the mutation spectrum of the FUS gene.

Objective:To evaluate the outcomes of intensive conservative treatment compared to conventional conservative treatment in patients with acute aortic syndrome(AAS).Methods:The study prospectively enrolled consecutive patients with AAS who were admitted to Beijing Anzhen Hospital, affiliated with Capital Medical University, and Beijing Dawanglu Emergency Rescue Hospital from January 2024 to December 2024. These patients with surgical contraindications or refused surgery for various reasons opted for conservative treatment. A total of 282 patients were included, and 15 patients with missing data or those who died without any treatment were excluded. Finally, 267 patients were enrolled, of whom 94 received intensive conservative treatment, and 173 received conventional conservative treatment, the inverse probability of treatment weighting (IPTW) was used to reduce the influence of confoundings. After adjusting of baseline datas via IPTW, the survival outcomes of the two groups were compared at 14 days, 30 days, and at the end of follow-up.Results:The results showed significant differences in acute phase survival rates between the enhanced conservative treatment group and the conventional conservative treatment group at 14 days(82.40%vs.53.20%, P<0.0001). Significant survival differences were also observed at 30 days and at 276-day mid-term follow-up (96.29% vs.51.60%, P<0.0001; 78.50% vs.48.50%, P<0.0001). In the subgroup analysis, for type A aortic dissection, the enhanced conservative treatment group had higher survival rates compared to the conventional conservative treatment group at 14, 30 and 276 days (63.46% vs.41.35%, P<0.05; 52.17% vs.37.90%, P<0.05; 50.00% vs. 31.97%, P<0.05). However, for type B aortic dissection, although the enhanced conservative treatment group had higher survival rates than the conventional conservative treatment group, no statistically significant differences were observed (96.29% vs. 80.00%, P=0.054; 95.65% vs.78.37%, P=0.067; 94.12% vs.74.20%, P=0.088). Conclusion:For patients diagnosed with AAS are forced to choose conservative treatment if emergency surgery is not possible in the first place, intensive conservative treatment strategies can significantly reduce the mortality in the acute phase compared with conventional conservative treatment. Mid-term follow-up, intensive conservative treatment still has a significant survival advantage.

Objective:To investigate the clinical and genetic characteristics of spinal muscular atrophy (SMA) patients with SMN1 gene compound heterozygous mutations. Methods:Three SMA-Ⅲ pedigrees treated in Henan Provincial People′s Hospital from October 2019 to July 2020 were selected. The clinical data of 3 SMA-Ⅲ probands were retrospectively analyzed. Multiplex ligation-dependent probe amplification (MLPA) technology was used to detect the copy number of the SMN gene in the probands and their parents. Polymerase chain reaction amplification combined with microfluidic capillary electrophoresis were used to detect point mutations in the SMN1 gene of the probands. Sanger sequencing was used to validate candidate variant sites. Results:The 3 probands are all male, aged 19, 17 and 12 years, respectively. The main clinical manifestations were symmetrical muscle weakness mainly in the proximal lower limbs, mild to moderate elevation of serum creatine kinase, and neurogenic injury as determined by electromyography or muscle pathology. The genetic testing results showed that all 3 probands had heterozygous deletion in exon 7 of the SMN1 gene, and carried heterozygous variations c.275G>A (p.Trp92 *), c.689C>T (p.Ser230Leu), and c.708dupT (p.Pro237Serfs *19), respectively. The exon deletion and point mutation were inherited separately from their parents. c. 275G>A (p.Trp92 *) and c.708dupT (p.Pro237Serfs *19) variations had not been reported before. Conclusions:The clinical manifestations of SMA-Ⅲ patients are symmetrical muscle weakness, mainly in the proximal extremities of both lower limbs, and electromyography or muscle biopsy suggesting neurogenic lesions. The compound heterozygous variation of point mutation and heterozygous deletion in the SMN1 gene can lead to SMA-Ⅲ. Suspected SMA patients with SMN1 gene heterozygous deletion should take point mutation testing.

Objective:To analyze the clinical manifestations and muscular magnetic resonance imaging (MRI) features of 12 families with facioscapulohumeral muscular dystrophy (FSHD).Methods:Retrospective analysis was conducted on 12 FSHD families diagnosed by genetic testing at the Department of Neurology of Henan Provincial People′s Hospital from January 2017 to June 2021. Clinical data and lower limb muscle MRI results of the probands and related members of the families were collected, and the degree of muscle fatty degeneration shown in the MRI was scored using the modified Mercuri score.Results:There were 21 patients in 12 families, with the age of onset ranged from 10 to 47 years (mean 19.5 years). The course of disease ranged from 1 to 47 years (mean 23.1 years). The onset sites included unilateral upper extremity in 8 cases, bilateral proximal upper extremities in 9 cases, bilateral proximal lower extremities in 2 cases, unilateral proximal lower extremity in 1 case, and simultaneous onset in all 4 limbs in 1 case. Sixteen patients had limb weakness and bilateral asymmetry, and 11/16 cases were more severe on the right side than the left side. Winged scapular and facial muscle weakness were observed in all patients. The creatine kinase range was 85-1 038 U/L (461 U/L on average) in 12/21 cases. There were 10/21 cases of myogenic lesion in electromyography. Myodystroph-like pathological changes were found in 11/21 cases. The fragment length of the 4q35 subtelomere polymorphism EcoRI/p13E-11 was less than 38 kb in 20/21 cases; 1 case was confirmed based on clinical symptoms and family history. Fat infiltration occurred in at least one muscle of lower limbs in 9/10 cases, in thigh muscle in 9/10 cases and in calf muscle in 6/10 cases. The average score of fat infiltration in thigh muscle group was higher than that in calf muscle group. The muscles with higher fat infiltration scores were the vastus intermedius, the long head of the biceps femoris, the vastus medialis, the vastus lateralis, the semitendinosus, the semimembranosus, the vastus lateralis in the thigh (with score ≥2.15), the tibialis anterior, and the medial head of the gastrocnemius in the calf (with score ≥1.11). Fat infiltration in the medial and posterior thigh muscles was more common than in the anterior thigh muscles. There was asymmetry of bilateral muscle fat in 9/10 cases. There were edematous changes in thigh muscles in 1 case and in calf muscles in 3 cases.Conclusions:The age of onset of FSHD patients is mostly ≤30 years. Bilateral asymmetric involvement is the characteristic manifestation of FSHD. The FSHD patients ' muscles most affected by the disease in the thigh are the quadriceps femoris, the long head of the biceps femoris, the vastus medialis, the vastus lateralis, the semitendinosus, the semimembranosus, and the vastus intermedius. In the calf, the muscles most affected are the anterior tibial muscle and the medial head of the gastrocnemius. The MRI pattern of muscle involvement of patients with FSHD is bilateral asymmetrical lesions, with the right side having more severe lesions. The fatization of thigh muscles is more significant than that of calf muscles, and the asymmetry of fatization between bilateral muscles is also present.

Objective:To investigate clinical, lower limb muscle magnetic resonance imaging (MRI) and myopathological features in hereditary caveolinopathy patients.Methods:Clinical data, lower limb muscle MRI and pathological findings of 2 patients with caveolinopathy diagnosed by genetic examination in Henan Provincial People′ s Hospital in January 2020 and August 2022 were retrospectively analyzed. And the characteristics of patients with hereditary caveolinopathy reported in China were analyzed in combination with literature review.Results:Case 1 was a 14-year-old boy. At 4 years old, his right heel did not touch the ground while squatting, and at 11 years old, he experienced weakness in his lower limbs and muscle pain during running, as well as difficulty in lifting his feet while walking. Six months earlier, he underwent surgery for right high-arched foot. Physical examination revealed slight atrophy of both first interosseous muscles, hypertrophy of the left calf, decreased muscle strength in the right distal leg, percussion-induced muscle mounding, postoperation of right high-arched foot, left high-arched foot as well as bilateral ankle contracture, foot drop, and inversion. Case 2 was a 15-year-old girl. At 14 years old, she presented prolonged exercise myalgia. Physical examination showed no positive signs. Both patients had no family history. Creatine kinase was slightly elevated in the 2 patients. Electromyography in the 2 patients showed a myopathic pattern in distal and proximal muscles. T 1-weighted MRI of lower limb muscles showed significant fatty infiltration in the bilateral rectus femoris, bilateral semitendinosus muscles, right tibialis anterior, right peroneus and right gastrocnemius lateral head in case 1. Selective rectus femoris muscle fatty infiltration in the thighs and mild gastrocnemius fatty infiltration in the lower legs were observed in case 2. Short inversion recovery sequence showed edema-like changes in both patients. Muscle pathology of both patients showed dystrophic-like pathological changes. A total of 9 Chinese patients with hereditary caveolinopathy reported in previous literature and in this study had an onset age from early childhood to youth. The main clinical manifestations were slowly progressive distal limb muscle weakness and atrophy accompanied by myalgia or merely presenting as myalgia. The creatine kinase levels were mildly to moderately elevated. Electromyography could show myogenic damage, myogenic and neurogenic mixed damage or normality. The muscle pathology showed myopathy-like or muscular dystrophy-like changes. Conclusions:The clinical manifestations of hereditary caveolinopathy are heterogeneous, and exercise-induced myalgia is frequently the most prominent symptom. The rectus femoris and gastrocnemius muscles tend to show early fatty infiltration in legs on MRI. Muscle pathology lacks specificity.
